HL 320.04 Evacuated tube collector
The HL 320.04 trainer contains a modern evacuated tube collector and allows you to convert solar energy into heat. Evacuated tube collectors reach much higher operating temperatures compared to simple flat collectors due to the lower thermal losses.
HL 320.04 is one of the modules from the HL 320 Solar thermal energy and heat pump modular system. The trainer can be incorporated into the modular system in a variety of different ways. The trainer can be used both for generating heated domestic water and for the combined production of domestic hot water and for heating rooms.
Pipe connections for the heat transfer fluid are easy to create and alter thanks to the quick-release couplings.
Carefully structured instructional materials have been created for the intended modular combinations with the HL 320.04 module. As part of the documentation for the HL 320 modular system, these materials set out the basic principles and provide a step-by-step guide through the experiments.
